Reiserfs was a bit slower than ext2, but not by that much - on bonnie++ I saw numbers like ~19MB/s reads from ext2, and about 16-17MB/s reads from reiserfs. This is on a disk that hdparm -t lists as giving about 21MB/s from the platters. I can't remember about writes, but I think it was slower there too - I may have had tail packing enabled, though,which would screw with the numbers.
The real test will be how it performs with a) lots of small files, and b) big files: reiserfs has always been better at dealing with lots of small files than ext2 (which isn't saying much, and with directory indexing ext3 looks to be as fast), but it's had problems with very large files, and it's tended to have problems with fragmentation leading to performance degredation over time. If they've dealt with those problems, then I could see "100% faster" being a reasonable description, assuming of course it /is/ that much faster.
Of course, I'm not going to trust my data to Reiser4 until it's been in real use for a while . . . Maybe 2.6.5 or so ;-)
